Is Pulmonary Artery Regurgitation the Knight in Shining Armor for a Young Adult Patient With Congenital Aortopulmonary Window?

Abstract

Aortopulmonary window in adults without signs of heart failure or pulmonary hypertension is exceptionally rare. We report here a case of a 27-year-old Caucasian male patient who presented with ventricular tachycardia and loud laterosternal systolic murmur due to a 9 mm aortopulmonary septal defect type 1, diagnosed for the first time. Echocardiography examination also revealed moderate pulmonary artery regurgitation. Pulmonary artery regurgitation may have served as the knight in shining armor in this extremely rare asymptomatic adult patient with aortopulmonary window, since a large amount of blood that enters the pulmonary trunk from the aorta redirects toward the right ventricle. Ventricular tachycardia may be the sole clinical presentation in an adult patient with aortopulmonary window and moderate pulmonary window.
